Liquid helium is the correct answer. It's got the lowest boiling point of any known substance and only solidifies under pressure, even at a fraction of a degree above absolute zero. Although nobody has observed this experimentally, atomic hydrogen, H not H2, should stay gaseous right down to absolute zero.

Liquid helium; it's much colder than liquid nitrogen, and much safer to work with that liquid hydrogen. Look up the history of cryogenics, the study of low temperatures.

umm we havnt ever made anything as low as possible. weve gotten to a few poitns of it but its noit. But there are quite a few cold things. Liquid nitrogen. Freon.dry ice and all that stuff. anything colder then thos thigns u wont beable to get ur hands on lol because its probly very rrare and hard to concentrate by itself lol ok good luck.
